[aprssig] Telemetry

[Robert Bruninga]

TInytrack-4 has 5 analog input channels and a telemetry beacon.  A 10k/2.4k
voltage divider for the volts channel will give  you the Volts in tenths
(up to 25.5 volts).  Reasonably enough.

Current either needs a current chip or you can do something with a
transistor to amplify the voltage drop across a shunt.

Hello



Need a hand – have a 10 GHz beacon we would like to add telemetry to



+ Temp

+ Current

+ Volts

+ RF 1

+ RF 2



Suggestions ?



Opentracker ?

TinyTrak ?



Want to send telem packet
